Motul 5100 vs 7100

I run cheap dino oil. Always have. Over 4 decades and 15 bikes the only oil related problem I had was spinning a crank bearing because I was playing in the red zone while down a quart or so.
lol...too funny. Wonder why you were down "a quart or so"? Keep using that cheap dino...lol....

So buying expensive oil will help me check my oil level more often. Who knew?
 
Just change the oil and filter every 5000k ( unless your racing).
Motul, amsoil, rottelaT5 or 6 is all good.
I'm sure all premier brands of oil never had an engine failure if there is no abuse.
 
Looking at the post title and the replies in this thread, still unclear as to the advantages (or disadvantages) of each Motul brand and why Motul and not Liquimoly or other brand?

Other than "abuse" I've never had a failure with the cheap dino (cars or bikes)
 
i literally just put liqui molly in one of my bikes lol. whats the big issue?
I've now done about 700 kms since I put in liquimoly 10w40 full synthetic, and it seems fine so far. Bike shifts identically to how it always has. Whatever issue the other guy had, it's probably unique to his bike.

Motul oil comes in three categories:

5100 - semi-synthetic
7100 - full synthetic
300V - full synthetic race

I use 300V in my GSX-R 1000 with such a high performance, high revving engine. No brainer.

7100 in my thumper (some use 300V (I think it's overkill)).

I was wondering how people were getting along with 5100 which IMO should be perfectly fine for a low revving twin. Turns out the 5100 is perfectly suited to the bike I was putting it in (Aprilia Dorsoduro).

Oil threads are mostly opinion and can go on and on forever. This one was Motul specific, overkill vs underkill, and was time specific (2022) as oil prices spiked and as such Motul prices were going through the roof.

The 300V is an Ester oil, and I wouldn't use it in a street bike. It is designed for racers and doesn't have the viscosity stabilizers and detergents like a "street" oil does.

as previously said, 300v is meant to be run for a race weekend and changed.
 
Yep, a whole bunch of "opinion", with tons and tons of regurgitated marketing BS
and very few facts
Both are Ester blends. 7100 is a single Ester, 300V is a double Ester for race applications. A GSX-R 1000 WOT on the track is in need of friction modifiers that the 300V provides, not detergents as it's changed often. But thanks for your opinion.

Another interesting fact is Motul has a shelf life of three years. Make sure you don't stock pile it and end up with degraded oil. Don't store it in a hot garage in the summer...in a cool basement is best. I did this once...expensive mistake. I ended up using it in my lawnmower...I couldn't kill that lawnmower...and still can't.

lol again...yes and no. It could have helped with not creating low oil levels in the first place IF you had used it from the start because it protects against engine wear better. ;-) But now your oil consumption will only get worse so you'll have to check it even more often. Next time, use syn from the start. ;-)
 
Not worried about oil consumption - that bike left a long time ago.
I'll just stick to the cheap dino and try to keep an eye on the sight glass. (Sight glass: Thanks Kawi!!)
